I have a 3/60FC and I just moved from 3.5 to 4.0.3.  I gave myself 32MB
disk space for a product called leonardo (big rasterfiles), and have had,
at times, disasterous slowdowns.  The OS seems very solid, and is nicer in
many ways, but I'm goin to have to buy at least double the 4MB I currently
am crawling with.  Occasionally.  ('Frinstance, when I get a submission to
a mailing list of 35.)

>diskless, is there a significant increase in ethernet traffic under 4.0.x?

More later when I get 4.0.3 up on a 3/160C & 3/50 in the next couple of
days ...
